Classify the substances according to the strongest solute-solvent interaction that will occur between the given substances and w
-BARSIC- [3]

Explanation:

Ion-dipole interactions are defined as the interactions that occur when an ion interacts with the dipole of a molecule (polar molecule).

For example, CuCl_{2}, CuSO_{4}, CaCl_{2}, NaCl etc are all the molecules that will show ion-dipole interactions.

Dipole-dipole interactions are defined as the interactions that occur when partial positive charge on an atom is attracted by partial negative charge on another atom.

When a polar molecules produces a dipole on a non-polar molecule through distribution of electrons then it is known as dipole-induced forces.

For example, NH_{3}, CH_{3}OH etc are the molecules which show dipole-dipole interactions.

6. If concentrations measured in moles per liter, and time in seconds, what are the units of the rate constant for (a) a first o
kaheart [24]

Answer:

(a) a first order reaction = s^-1.

(b) a second-order reaction = L(mol·s)

(c) a third-order reaction = s⁻¹M⁻²

Explanation:

Okay, this question is a question that has to do with kinetics that is how reaction occurs.

So, the RATE LAW is one of the concept that is being used in determining conditions of chemical reactions. The relationship between the the reactants molarity and the reaction rate is known as rate law. That is to say;

Rate law = K × Molarity.

So, In this question we are given that the concentrations measured in moles per liter, and time in seconds.

The FIRST ORDER REACTION has its unit for rate constant as per seconds(s^-1).

That is from; Rate law = k

Molarity/s = k × Molarity.

k = s^-1

(b) a second-order reaction;

Rate law= k × (molarity)^2.

Molarity/s = k × (Molarity)^2.

k = L(mol·s)

(c) A third-order reaction = s⁻¹M⁻²

Same thing applies.
